MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049670 A) filed by Mahesh Bejugama; and Ch Jhansi Rani, Hyderabad, Telangana, on April 18, for 'hybrid electro-optic quantum architecture (heoqa).'
Inventor(s) include Mahesh Bejugama; and Ch Jhansi Rani.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The Hybrid Electro-Optic Quantum Architecture (HEOQA) addresses thermal and wiring scalability limitations in superconducting quantum processors by replacing metallic coaxial interconnects with optical fiber links via electro-optic transduction, reducing thermal load by over 10,000 per channel. The architecture comprises three stages: a millikelvin superconducting transmon qubit core, a 4K electro-optic transduction stage converting 5 GHz microwave signals to 193 THz optical photons using lithium niobate modulators, and a room-temperature Photonic Processing Unit performing passive unitary matrix operations via programmable Mach-Zehnder interferometer meshes. CTE-matched polyimide or gold/aluminum-coated silica fibers prevent microbending losses during thermal cycling. Hermetic vacuum feedthroughs eliminate moistureinduced fiber facet failures. Wavelength Division Multiplexing enables 100 independent qubit channels per fiber at ~1 Tbps aggregate throughput, reducing fiber count by 100. HEOQA enables practical superconducting quantum processors scalable beyond 10,000 qubits within commercially available cryogenic platform cooling budgets."
